Hi, somebody refered me to here as you may be able to help-i hope so! I have a Memorex STAV-3100 amplifier/receiver. All was working fine when it decided to go pop! The volume wasn't on high at the time, when i tried to switch it back on it blew the fuse in the plug, the fuse in the back of the amp next to the PSU was fine. I checked the output transitors and ALL were short along with one driver transistor, one of the biasing transistors had the side blown off! I have replaced all of those & the amp powered up OK. I noticed at this point that the volume meter was reading on the left channel even though the volume was off. I also noticed the amp seemed to be giving out massive(but clean!) bass! I switched it off and had a look over it, when i switched it back on it was dead & has blown the fuse in the plug again! I have the tech manual but the schematic is missing. I'm now at a loss, i can't see any physical damage or shorts, i need to check the transistors again but fear it has fried them again! There is no bias adjustment pot. Any help on where to go from here would be great! Thanks for reading.
